A special nodule 28 (see FIG. 13B) is used to manufacture the net 9.

  Here, in the case of special knotting 28 for the warp yarn 7 and the weft yarn 8, the net making machine 1 continuously performs the first wrinkle knot operation, the preparation operation, and the second wrinkle knot operation described below. In addition, when the warp yarn 7 and the weft yarn 8 are knotted or knotted 27, only the first knotted or knotted operation is performed.

  First, in the first heel or knot operation, as shown in FIG. 2, the lower heel 17 is brought into an initial state in which it is made to wait on the rear side (weft side) of the upper heel 16. At this time, the lower arm 22 is kept extended by the telescopic mechanism 24.

  Next, as shown in FIG. 3, the yarn swing 15 and the upper collar 16 cooperate to form a loop 29 of the warp thread 7 at the collar portion of the upper collar 16.

  Next, as shown in FIG. 4, the lower eyelid 17 (lower eyelid arm 22) is advanced while the lower eyelid arm 22 is extended by the telescopic mechanism 24, so that the flange portion 21 of the lower eyelid 17 The loop 29 of the warp 7 formed in the upper hook 16 is inserted through the insertion hole 20 to be in a state of being inserted.

  Next, as shown in FIG. 5, the warp thread 15 is brought into a state where the warp thread 7 is hooked on the collar portion 21 of the lower collar 17 by the action of the thread swing 15.

  Next, as shown in FIG. 6, the lower heel 17 (lower heel arm 22) is retracted, the warp thread 7 hooked on the heel portion 21 of the lower heel 17 is pulled out in a loop shape, the money 13 is hidden, The warp yarn 7 hooked on the collar portion 21 of the lower rod 17 is released at the lower rear portion of the money 13, whereby the weft yarn 8 supplied from the money 13 is beaten with the warp yarn 7. Here, since the shrinkage of the warp yarn 7 differs depending on the influence of humidity, temperature, material, etc., the encoder is controlled so that a certain amount of warp yarn 7 is always drawn out by the lower rod 17.

  By the operation up to this point, the first strut or knot operation is completed. Thereafter, when the seam is tightened (see FIG. 12), the warp yarn 7 and the weft yarn 8 are ligated and knotted 27 as shown in FIG. 13 (a).

  Next, in the preparatory operation, the operation in the direction opposite to the first heel or knot operation is performed without performing the eye-tightening. That is, as shown in FIG. 7, the lower rod 17 (lower rod arm 22) in a state where the lower rod arm 22 is extended by the expansion / contraction mechanism 24 with the loop 29 of the warp thread 7 formed in the collar portion of the upper rod 16. Move forward.

The insertion hole 20 of the upper hook 16 is not inserted (the loop 29 of the warp 7 formed on the upper hook 16 is not inserted).

  Next, as shown in FIG. 9, the yarn swing 15 is idled, and then the lower eyelid arm 22 is extended by the expansion / contraction mechanism 24 so that the eaves portion 21 of the lower eaves 17 passes through the insertion hole 20 of the upper eaves 16. The loop 29 of the warp yarn 7 formed on the upper hook 16 is inserted.

  The preparatory operation is completed by the operation so far, and thereby, the state returns to the same state as that shown in FIG. 4 in the first rod and knot operation, and the operation in the same direction as the first rod and knot operation is continued. Do.

  That is, as shown in FIG. 10, the warp thread 15 is used to hook the warp thread 7 on the heel part 21 of the lower heel 17, and then, as shown in FIG. ) Is retracted, the warp thread 7 hooked on the collar part 21 of the lower collar 17 is pulled out in a loop shape and the money 13 is hidden, and the warp thread 7 hooked on the collar part 21 of the lower collar 17 at the lower rear part of the money 13 Thus, the weft 8 supplied from the monetary 13 is scooped with the warp 7. Here, since the shrinkage of the warp yarn 7 varies depending on the influence of humidity, temperature, material, etc., the encoder is controlled so that a certain amount of warp yarn 7 is always drawn out by the lower rod 17.

  By the operation up to this point, the second rod or knot operation is completed. Thereafter, as shown in FIG. 12, the upper hook 16 is tilted to release the loop 29 of the warp 7 from the hook 21 and the seaming mechanism 12 is operated to close the thread, and then the warp is fed by a predetermined amount. The mechanism 11 and the eye feed mechanism 25 are operated.

  As a result, as shown in FIG. 13 (b), the warp 7 and the weft 8 are specially knotted 28 in a special shape in which the warp 7 and the weft 8 are more entangled than the knot or knot 27.

  As described above, in the net making machine 1, the warp 7 and the weft 8 can be hooked and knotted 27 by performing the net making method by the first hook or knot operation, and the first hook or knot 27 The warp yarn 7 and the weft yarn 8 can be specially knotted 28 by performing a net making method in which a preparatory operation and a second cocoon knotting operation are performed following the knotting operation.

  In the net making machine 1, the cocoon knot 27 and the special knot 28 can be alternately performed, a desired part of the net 9 can be special knotted, and the other part can be knotted knot 27. It is also possible to manufacture the net 9 in which the cocoon nodule 27 and the special nodule 28 are mixed.

  Therefore, as shown in FIG. 14, when the rectangular net 9 is manufactured, the special nodule 28 is operated only at the beginning and the end, and otherwise, the operation of the nodule 27 is continuously performed. A nodule in the middle of one side of the edge triangular part 30 formed in a triangular shape at the edge of 9 is a special nodule 28, and an inner square part 31 formed in a square shape inside the edge of the net 9 It is also possible to produce a nodule nodule 27.
